Run LocalBackend on multiple nodes with :peer

[lorrrrrrrenzo]

Per issue #3 we use Erlang's :peer package to start another erl process, enabling local FLAME workers to run code distinct from the parent process.

As per #79 (comment) what are the requirements for this to be merged?

This is something we would like to be in, as far as I know. So once it is ready for review, one of FLAME maintainers will review when they have time available.

@lorrrrrrrenzo are you still active on Github? Wanted to know if it's ok to salvage for review.

[lorrrrrrrenzo]

Hello @fire. Yes, I'm still active on GH and would prefer to keep this PR. I think the most helpful thing would be to clone it and check whether the behavior conforms to what you expect and need from the tool. Once I get a moment to review this, I'll upgrade it to a proper PR for review by the core team.

Happy to collaborate.

I'm interested in getting this across the line for a work project, so please let me know if there's anything I can do. In the meantime, I will do as @lorrrrrrrenzo suggested and clone the changes to test it out myself and report back!
